As outlined on the NASH website, steel house frames must be permanently earthed in accordance with the requirements of the local electricity authorities. A temporary earth should be established until the permanent earth is installed.

An electric current will follow the path of least resistance, the amount of current being in inverse proportion to the resistances involved. In other words, if there are two paths the current can follow, it will split into two, the stronger current being conductive through the lower resistance. If that resistance is very low relative to the other, nearly all the current will flow through it. This is how the process of “earthing” works. Steel is an excellent conductor of electricity so it is improbable that any electric current would actually pass through a human body (high resistance) instead of the frame to earth system (low resistance). Non-conducting building materials with higher electrical resistances than steel actually increase the chance that more current will pass through the human. For more information on Electrical Safety, check the National Association of Steel-Frames Housing (NASH) website.

No. BlueScope Steel has worked exclusively with our paint suppliers to develop a coating solution that delivers the thermal benefits of COLORBOND® Coolmax® steel.

Wall and roof framing made from TRUECORE® steel is 100% termite and borer proof. Because of this, the frames don’t require additional chemical treatments to protect them from pest attack. TRUECORE® steel is also non-combustible, so its use significantly reduces the amount of flammable material in a home.

Using COLORBOND® Coolmax® steel not only results in cost savings from reduced ongoing operational costs but also has the potential to reduce up-front expenditure on HVAC cooling equipment. For an understanding of the possible savings for your particular commercial or industrial building, we refer you to the calculator.

Most fences feature galvanised steel posts and COLORBOND® steel infill sheets. Immersing the galvanised steel posts in concrete does not cause any corrosion problems but you should not allow the concrete to contact the rails or infill sheets of the fence. Check with your Supplier.

Yes. Samples of COLORBOND® Coolmax® steel in Whitehaven™ are available in a standard swatch size. Contact Steel Direct on 1800 022 999.

Your fence is very easy to maintain. Here's a few tips to make sure it keeps looking great.

• Wipe or hose it down regularly – at least once every six months or more if you live in a coastal area (water restrictions permitting). Pay particular attention to cleaning dirt or debris from under the top rail where rain doesn’t naturally wash.
• Remove cobwebs using a soft broom. This will deal with any spiders.
• Don’t let soil, dirt and garden debris build up at the base of the fence or next to the posts and rails. This will retain water and can lead to corrosion.
• Be careful not to spray the fence with garden chemical sprays or fertilisers as these can damage the surface. If this happens, wash the fence down with water immediately.
• Don’t use your fence as a retaining wall. It isn’t designed for this purpose.

There are several advantages associated with using COLORBOND® Coolmax® steel. These include, but are not limited to, the following:

• Air-conditioned commercial buildings may enjoy direct cooling benefits that typically pay back the costs many times over the life of the roof.
• Single story commercial buildings without air-conditioning are likely to be cooler in hot weather improving thermal comfort within the building.

COLORBOND® Coolmax® steel keeps the roof cooler leading to less thermal stress.

Specifying COLORBOND® Coolmax® steel over lower solar reflectance roofing materials also may help mitigate the impact of urban heat islands and can favourably impact the lifespan of roofing materials, see our test study.
